Cookie banner development

I will create a cookie banner for WordPress, Laravel, or a custom website. Cookie consents, blocking scripts before consent, Google Consent Mode v2, GA4, Meta Pixel, and technical measurement setup.

Cookie consent for websites

A cookie banner that actually solves something

Many websites today have a cookie banner, but realistically it blocks nothing. The banner is displayed, a person clicks "Reject", but Google Analytics or Meta Pixel is already running anyway. It is not just about how the banner looks, but mainly what it actually blocks and when the scripts are triggered.

I handle new cookie banners as well as fixes for existing ones. Whether it is WordPress, Laravel, or a regular corporate website, what is usually needed most is to check scripts, cookies, and set up consents properly.

Consents by category

Technical, analytical, or marketing cookies. The visitor should be clear about what they are consenting to.

Script blocking

GA4, Meta Pixel, or other tracking scripts should not load before the visitor approves the specific category.

Consent Mode v2

Integration of the cookie banner with Google Consent Mode v2 and correct passing of consent states to Google tools.

WordPress and Laravel

A plugin, a custom solution, or a combination of both depending on how the website is built.

What needs to be addressed

A "pretty banner" is not enough

Websites often run GA4, Meta Pixel, YouTube videos, maps, or various chat widgets. And this is exactly where the problem usually lies. The website may display a cookie banner, but some scripts have already been loaded long before the click.

Cookie banner settings

Texts, buttons, consent categories, cookie rejection, or the option to change settings later.

Script and cookie audit

I will find out what loads on the website right after opening the page and what should be blocked.

Google Analytics 4

Setting up analytics so that it respects the visitor's consent and does not run unnecessarily.

Meta Pixel

Facebook and Instagram tracking only after marketing cookies are accepted.

External services

Maps, videos, chat widgets, or remarketing scripts need to be dealt with individually depending on how they work.

Fixing an existing cookie banner

I often deal with websites where a banner exists but technically does not work correctly.

Technical setup

It is not just about making the banner appear on the screen

This is a terribly common problem. The website has a cookie banner, but analytics or ad scripts load right after the page opens. The visitor can then click "Reject", but part of the tracking has already taken place long ago.

That is why I do not just deal with the appearance of the banner, but mainly whether the entire solution really works correctly from a technical standpoint. The consent must be saved, settings must be reopenable, and scripts should trigger based on what the user allowed.

Process

How cookie banner setup works

Before addressing the banner itself, it is necessary to find out what the website actually loads. Only then does it make sense to deal with texts, buttons, categories, and the technical execution of scripts.

01

Website check

I go through tracking codes, external scripts, cookies, plugins and tools that run on the website.

02

Consent categorization

I determine what is technical, analytical, marketing or preference-related and how it should behave after rejection.

03

Cookie banner implementation

I prepare the banner, buttons, settings, storing of the choice and the option to change consent later.

04

Testing

I verify whether scripts do not run before consent and whether they behave correctly after the choice is changed.

Who cookie banner development is suitable for

Cookie banners are mainly needed for websites that use analytics, advertising systems, remarketing, embedded maps, videos, chats, forms or other external tools. Typically, these are company websites, e-shops, landing pages, WordPress websites, Laravel applications and online services that work with traffic tracking or advertising.

Company websites

Traffic tracking, forms, maps, contact elements and standard analytics tools.

E-shops

GA4, advertising systems, conversions, remarketing, product campaigns and marketing cookies.

WordPress websites

Plugins, builders, embedded codes, tracking scripts and adjustment of an existing cookie banner.

Laravel applications

Custom consent logic, storing settings, scripts by category and a tailored solution.

Frequently asked questions about cookie banner development

  • What is a cookie banner?

    A cookie banner is an element on a website that informs visitors about the use of cookies and allows them to allow, reject or adjust consent for individual types of cookies.

  • Is it enough to just install a cookie plugin?

    In many cases, no. The plugin might display a banner, but scripts can continue to run completely normally. Therefore, it is necessary to check what is actually loading before consent.

  • Can you create a cookie banner for WordPress?

    Yes. With WordPress, I usually handle plugins, tracking codes, GA4, Meta Pixel, embedded scripts, and ensuring everything triggers only based on consent.

  • Can you create a cookie banner for Laravel?

    Yes. With Laravel, a custom solution can be prepared for saving consent, category division, and conditional script execution.

  • What does blocking cookies before consent mean?

    It means that selected analytical or marketing scripts do not run immediately when the page loads, but only after the appropriate consent has been granted.

  • Can a cookie banner be connected to Google Consent Mode v2?

    Yes. This is most commonly done for GA4 or Google Ads, so that Google knows whether the visitor allowed analytical or marketing cookies.

  • Do you also handle Google Analytics and Meta Pixel?

    Yes. The setup can include GA4, Google Ads, Meta Pixel, remarketing, and other tracking or marketing scripts.

  • Can you also check an existing cookie banner?

    Sure. I often deal precisely with websites where a cookie banner exists but does not work correctly technically. I will check cookies, external scripts, GA4, Meta Pixel, and whether anything triggers before consent.

  • Is a cookie banner important for a company website as well?

    Yes, if the website uses analytics, advertising, maps, videos, chat widgets, remarketing, or other external services, it makes sense to handle cookie consent even for a regular corporate website.

  • How much does cookie banner development cost?

    The price depends on the type of website, the tools used, the number of scripts, the Consent Mode v2 integration and whether it is a new solution or a modification of an existing cookie banner.

Do you want to set up a cookie banner on your website?

Write to me about what your website runs on, what tracking tools you use, and whether you already have a cookie banner. I will check the cookies, scripts, and prepare a solution for WordPress, Laravel, or a custom website.
